Abstract
A battery charger includes a housing, an electrical connector, magnets, and sensors. The electrical connector with a magnet attached thereon is received in the housing. The electrical connector is connected to the rear wall of the housing via an elastic member. The electrical connector is capable of extending out of the housing and through an opening in the housing. Another magnet is secured at a front end of the housing. When an attractive force is induced between the magnets, the electrical connector is extended towards and through the opening in the housing. The sensors are configured for detecting that a robot is in position to be charged and for turning on the attractive force between the magnets.
